Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to an adaptive adjustment heavy-duty pulley device for panoramic doors and windows. Background Technology

[0002] Currently, sliding doors and windows are opened and closed by installing pulley assemblies at the top or bottom of the door or window frame.

[0003] In existing sliding door and window pulley assemblies, such as the patented technology solution published in Chinese patent literature with patent number 202121760216.X and titled "A Two-Way Sliding Door Buffer and a Moving Door Frame," this solution mainly includes a housing and a first wheel group and a third wheel group disposed at both ends of the housing. The first wheel group and the third wheel group are respectively composed of a wheel frame, a wheel axle, a concave wheel, a spherical bushing, a sliding door mounting box, a connecting screw, a nut seat, and a nut. When the guide rail becomes deformed and uneven, the gap formed between the nut seat and the nut, and the spherical bushing, can automatically adapt to the swing adjustment. However, in practical applications, this pulley assembly still has the following shortcomings:

[0004] The gap formed between the spherical bushing, the nut seat, and the nut in this design only allows the concave wheels on both sides of the first and third wheel sets to perform an alternating up-and-down oscillation adjustment in the sliding direction, in order to solve the problem of uneven sliding caused by pitted deformation of the guide rail. However, when the guide rail deforms and becomes sloped, the first and third wheel sets cannot perform pitching and oscillation adjustment along the sliding direction, thus failing to glide smoothly over the sloped guide rail. Therefore, it can be seen that the adaptive adjustment range of this design is very limited.

[0005] Therefore, given the aforementioned shortcomings of existing pulley assemblies, the applicant believes it is essential to design a pulley device that can smoothly pass through a sloping guide rail in order to better meet people's practical application needs. Utility Model Content

[0006] The purpose of this invention is to solve the above-mentioned problems and shortcomings by providing an adaptive adjustment heavy-duty pulley device for panoramic doors and windows. This pulley device, by setting a swing bracket, can be transformed into a device that allows the bracket to swing in the sliding direction when fixed on the door and window frame. This allows the bracket to slide smoothly over the sloping guide rail and ensures that the sliding door and window will not bounce up and down, thus ensuring the smooth movement of the sliding door and window. Furthermore, by setting a spherical bushing, the pulleys on the left and right sides of the bracket in the length direction can be adjusted by alternating up and down jumping. Through the above two adaptive adjustment actions, the adaptive adjustment range of the pulley device can be greatly improved to ensure smooth sliding without abnormal noise.

[0007] The technical solution of this utility model is implemented as follows: A heavy-duty adaptive adjustment pulley device for panoramic doors and windows, characterized in that it includes a support base, which further includes a left half support and a right half support that are divided along its length and can be interlocked into a whole. A spherical bushing is clamped at both ends of the left half support and the right half support, and is laterally inserted. An axle is fitted onto the spherical bushing, and pulleys are installed at both ends of the axle, with the pulleys positioned on the sides of the support base. A swing bracket connected to the door / window frame is provided, with a lower extension in the middle. The lower extension is clamped and hinged at the middle position between the left half support and the right half support, allowing the swing bracket to adaptively swing and adjust at both ends along the length of the support base.

[0008] Preferably, the left half bracket and the right half bracket are respectively provided with an extension on the outer side of both ends, and a guide pulley that rotates horizontally in the circumferential direction is provided on the extension.

[0009] Preferably, the bottom surface of the extension portion is further provided with a brush component.

[0010] Preferably, the inner surfaces of the left and right half brackets are respectively provided with positioning protrusions and protrusion holes, and pin shafts and pin shaft holes for fastening the two together as a whole.

[0011] Preferably, the left and right halves of the bracket are respectively provided with fitting holes for the spherical bushing to be received and fitted, and the fitting holes are configured such that the inward-facing cavity is larger than the outward-facing cavity.

[0012] Preferably, the outer surfaces of both ends of the left and right half-supports are respectively provided with concave wheel cavities for accommodating pulleys.

[0013] Preferably, the swing bracket is a long and flat slat, the lower extension is integrally formed from the middle of the bottom surface of the slat, and a swing shaft hole is provided on the lower extension. A rubber bushing is fitted into the swing shaft hole, and the left half bracket and the right half bracket are also provided with hinge holes correspondingly.

[0014] Preferably, the top surface of the slat body along its length is further provided with a raised rib, and vertical screw holes penetrating the raised rib are also provided at both ends of the slat body.

[0015] The beneficial effects of this utility model are as follows: By setting a swing bracket that can adaptively swing at both ends along the length of the bracket base, in application, the swing bracket is fixed to the door and window frame, which transforms the bracket base into a pitching swing adjustment in the sliding direction. This allows the bracket base to smoothly slide over the sloping guide rail, and ensures that the sliding door and window does not bounce up and down when sliding over the sloping guide rail, thus ensuring very smooth movement of the sliding door and window. Furthermore, the setting of the spherical bushing allows the left and right pulleys on both sides of the bracket base to perform an alternating up and down jumping swing adjustment, solving the problem of uneven sliding caused by pitted deformation of the guide rail. Through the above two adaptive adjustment actions, the adaptive adjustment range of the pulley device can be greatly improved, ensuring smooth sliding without abnormal noise. At the same time, the setting of the left and right half brackets can clamp the spherical bushing to prevent it from loosening, thereby improving the reliability of the assembly connection.

[0022] like Figure 1 and Figure 3As shown, the adaptive adjustment heavy-duty pulley device for panoramic doors and windows of this utility model includes a support base 1, which further includes a left half support 11 and a right half support 12 that are divided along its length and can be interlocked into a whole. A spherical bushing 3, arranged laterally, is clamped at both ends of the left half support 11 and the right half support 12. A wheel axle 4 is fitted onto the spherical bushing 3, and pulleys 2 are installed at both ends of the wheel axle 4, with the pulleys 2 positioned on the sides of the support base 1. A swing bracket 5 connected to the door / window frame has a lower extension 51 in its middle. The lower extension 51 is clamped and hinged at the middle position between the left half support 11 and the right half support 12, allowing the swing bracket 5 to adaptively swing and adjust at both ends along the length of the support base 1. The pulley device of this utility model can be installed at the top of the door / window as a hanging pulley component or at the bottom of the door / window as a bottom pulley component. Preferably, the present invention uses the pulley device fixed at the bottom of the door or window as a bottom pulley component, which is more suitable for heavy-duty panoramic doors and windows.

[0023] When the guide rail has a guide cavity, and the guide rail track is located at the bottom of the guide cavity, or when the guide rail is a strip guide box, in order to prevent the pulley device from derailing, such as Figure 2 As shown, the left half bracket 11 and the right half bracket 12 are respectively provided with an extension portion 13 on both outer sides, and a guide pulley 14 that rotates horizontally in the circumferential direction is provided on the extension portion 13. This allows the guide pulley 14 to move along the inner cavity side wall of the guide rail, preventing derailment.

[0024] During the sliding process, in order to clean up small debris in the guide rail track and ensure smooth and even sliding, such as Figure 2 As shown, a brush component 15 is also provided on the bottom surface of the extension portion 13. This allows for cleaning of the guide rail track during both forward and backward movement, ensuring high reliability. In practical applications, such as... Figure 3 As shown, the extension portion 13 is provided with a T-shaped groove 131, and the brush component 15 is provided with an insert portion 151 that is embedded in the T-shaped groove 131. In order to prevent the insert portion 151 from dislodging from the T-shaped groove 131, a clamping block 152 is also provided between the insert portion 151 and the T-shaped groove 131.

[0025] To facilitate quick positioning for assembling the left half bracket 11 and the right half bracket 12, and to easily fix the left half bracket 11 and the right half bracket 12 together, such as Figure 3 and Figure 4As shown, the inner surfaces of the left half-bracket 11 and the right half-bracket 12 are respectively provided with a positioning protrusion 16 and a protrusion hole 17, and a pin 18 and a pin hole 19 for interlocking the two into a whole. Specifically, the positioning protrusion 16 is provided on the outer extension 13 of the left half-bracket 11, and the protrusion hole 17 is provided on the outer extension 13 of the right half-bracket 12; of course, the positions of the positioning protrusion 16 and the protrusion hole 17 can also be interchanged to achieve the same purpose of quick positioning. Both the left half-bracket 11 and the right half-bracket 12 are provided with pin holes 19, and the two ends of the pin 18 are respectively fixed in the pin holes 19 of the left half-bracket 11 and the right half-bracket 12. In practical applications, the pin 18 can also be replaced by a rivet. Screws or screw holes can also replace the pin 18 and the pin hole 19.

[0026] To prevent the spherical bushing 3 from loosening and falling off, such as Figure 4 As shown, both ends of the left half bracket 11 and the right half bracket 12 are respectively provided with fitting holes 20 for the spherical bushing 3 to be received and fitted. The fitting holes 20 are configured such that the inward-facing cavity is larger than the outward-facing cavity. This can confine the spherical bushing 3 between the fitting holes 20 of the left half bracket 11 and the right half bracket 12, preventing the spherical bushing 3 from loosening and falling off.

[0027] In order to reduce the overall size of the pulley system, such as Figure 3 and Figure 4 As shown, the outer surfaces of both ends of the left half bracket 11 and the right half bracket 12 are respectively provided with concave wheel cavities 21 for accommodating pulleys 2.

[0028] To further improve the structure of the swing bracket 5, the left half bracket 11, and the right half bracket 12, such as... Figure 3 and Figure 5 As shown, the swing bracket 5 is a long, flat slat. The lower extension 51 is integrally formed from the center of the bottom surface of the slat. A swing shaft hole 52 is provided on the lower extension 51, and a rubber bushing 53 is fitted into the swing shaft hole 52. The left half bracket 11 and the right half bracket 12 also have corresponding hinge holes 56. By integrally forming the lower extension 51 and the swing bracket 5, the connection structure between the lower extension 51 and the swing bracket 5 has higher strength, and the connection is less prone to breakage. In actual installation, the lower extension 51 is hinged to the left half bracket 11 and the right half bracket 12 by passing the hinge shaft 561 through the rubber bushing 53 in the hinge hole 56 and the swing shaft hole 52, respectively. The rubber bushing 53 prevents scraping noise between the swing shaft hole 52 and the hinge shaft 561, resulting in quieter operation.

[0029] To further increase the structural strength of the swing bracket 5, prevent its breakage, and facilitate the connection of the swing bracket 5 to the door and window frame 551, such as... Figure 5 and Figure 6 As shown, the top surface of the slat body along its length is also provided with a raised rib 54, and vertical screw holes 55 penetrating the raised rib 54 are provided at both ends of the slat body. During installation, screws 550 are passed through the vertical screw holes 55 and locked into the door and window frame 551, thereby fixing the swing bracket 5 to the door and window frame 551.
